It can be somewhat unsettling to realize that an animal you may think of as a literal birdbrain is, at least within a particular environment or framework, a little smarter than you realized or maybe even a little smarter than you.
Anyone who's ever watched a dog remove an unwanted collar or cone won't be amazed by that. I was intrigued that not only was a Magpie able to remove the tracking device but also that a Magpie was somehow able to communicate its distress to others of its kind who were interested enough to stop whatever they were doing and assist their brother or sister in precisely the method required.
“We were literally packing up our gear and watching it happen.” In a remarkable act of cooperation, the magpie wearing the tracker remained still while the other magpie worked at the harness with its beak.
Within 20 minutes, the helping magpie had found the only weak point — a single clasp, barely a millimeter long — and snipped it with its beak. Dr. Potvin and her team later saw different magpies removing harnesses from two other birds outfitted with them. The scientists took six months to reach this point. Within three days, the magpies had removed all five devices. LINK
But apparently no one should be surprised. Magpies are part of the corvid family (this includes crows and ravens) and are considered to be among the smartest animals on the planet. Their brain to body weight ratio is just below that of humans. As we learn more about bird intelligence and the brain power of many other animals perhaps we will consider new ways to live in harmony with such creatures and not heedlessly destroy their environments or kill them for amusement.
